Lincoln Electric IM943 POWER WAVE i400 - Manual (Page 33)

INTERNAL CONTROLS DESCRIPTION
1. MAIN RECONNECT: Selects main capacitor configura-
tion for 208-230V or 380-575V input.
2. AUXILIARY RECONNECT: Configures auxiliary power
for specified input voltage (208/230/380/460/575V).
3. FUSE (F1): Primary circuit protection for auxiliary power
(10A/600V).
4. ROBOT POWER TERMINAL BLOCK (4TB): Power sup-
ply connection for Fanuc R30iA / R30iB controller.
Supplies primary power through the ON/OFF switch
directly to the robot controller.
This input power pass-through connection is intended
to supply power exclusively to the Fanuc R30iA / R30iB
controller. It is designed to support a 3kW maximum
robot controller load through cable provided with the
K2677-2 Integration Kit.

ELECTRIC SHOCK CAN KILL.
DO NOT ATTEMPT TO BACK FEED INPUT
POWER THROUGH THE ROBOT POWER
TERMINAL BLOCK (4TB) INTO THE POWER
WAVE I400.
THIS IS NOT ITS INTENDED PURPOSE, AND MAY
RESULT IN MACHINE DAMAGE, BODILY INJURY OR
DEATH.

5. CHASSIS POWER TERMINAL BLOCK (3TB): Power connec-
tion for internal chassis. Provides power for the inverter and all
auxiliary supplies.
6. INPUT POWER TERMINAL BLOCK (1TB): Input power connec-
tion from main service disconnect.
7. GROUND TERMINAL: Earth ground connection.
8. PC BOARD DIPSWITCHES (NOT SHOWN): PC Board dip-
switches are set at the factory to allow configuration of the
POWER WAVE
® i400 via the Fanuc Teach Pendant or with the
Weld Manager Utility (included on the POWER WAVE ® Utilities
and Service Navigator CDʼs or available at www.powerwavesoft-
ware.com). The factory default settings are as follows:
Control Board (G4800 Series Hardware):
• S1
large
= OFF
• S2
small
= ON
Feed Head Board (L11087 Series Hardware):
• S1
1 thru 8
= OFF
POWER-UP SEQUENCE
The POWER WAVE ® i400 will typically be powered up at the same
time as the robotic controller. The status lights will blink green for
about a minute while the system is configuring. After this time, the
status lights will turn a steady green indicating the machine is ready.
DUTY CYCLE
The POWER WAVE ® i400 is rated at 350 amps at 31.5 volts with
a 100% duty cycle. It is further rated to provide 400 amps at 34 volts
with a 60% duty cycle and 420 amps at 35 volts with a 40% duty
cycle. The duty cycle is based on a ten-minute period. A 60% duty
cycle represents 6 minutes of welding and 4 minutes of idling in a
ten-minute period.
Note:
The
POWER WAVE ® i400 is capable of producing a peak output
current of 700 amps. The allowable maximum average output cur-
rent is time dependent, but ultimately limited to 450 amps over any
2 second period. If the maximum average is exceeded, the output is
disabled to protect the machine. Under these conditions, normal
operation can be resumed by cycling the output command.
COMMON WELDING PROCEDURES
MAKING A WELD
The serviceability of a product or structure utilizing the weld-
ing programs is and must be the sole responsibility of the
builder/user. Many variables beyond the control of The Lincoln
Electric Company affect the results obtained in applying these
programs. These variables include, but are not limited to, weld-
ing procedure, plate chemistry and temperature, weldment
design, fabrication methods and service requirements. The
available range of a welding program may not be suitable for
all applications, and the build/user is and must be solely
responsible for welding program selection.
